Equipment
- Stages: sediment, carbon, membrane, post-filter, alkaline remineralization.
- Tank or compact design, depending on cabinet space.
- Certification claims under NSF/ANSI 58 that match what you care about.
Living Water's alkaline RO adds a remineralization stage after the membrane, which is part of both the equipment and the filter schedule. A tankless design can save cabinet space; see tankless vs. tank RO.
Installation in Miami Shores kitchens
| Factor | Effect |
|---|---|
| Countertop material | Granite, quartz or tile may need careful drilling for the faucet |
| Cabinet depth | Older cabinets may suit a compact unit |
| Drain type and age | Affects the drain saddle connection |
| Fridge or ice maker | Extra tubing and fittings |
| Condo rules | Some associations set installation requirements |
Low water pressure is the other common add-on. If your home's pressure is low, a booster pump may be recommended, and the quote should explain why with the reading Jorge took.
Running costs
WASD's chloramine, reported at a 2.5 ppm average in 2025, is handled by the carbon pre-filter, which protects the membrane. Its replacement interval depends on your household's use. Ask for:
- Each filter's part number and interval.
- Membrane life under your conditions.
- Water sent to drain during production.
- Service options if you prefer not to change filters yourself.
See RO filter replacement cost.
Compare honestly
Add up what you spend now on bottled water or delivery, then compare with the filter schedule. Our bottled water vs. RO calculator helps.
Remember to count the time and trips as well as the money: carrying cases, storing them, and recycling bottles. For a household drinking several liters a day, those add up.
Quote checklist
- Exact model and certification listing.
- Labor and parts, itemized.
- Filter schedule and parts.
- Warranty for equipment and labor.
- Service contact.
Living Water offers financing through its financing partners; you apply with a credit application, and a co-applicant can apply with you.
Ask also how the system is installed: Living Water installs the systems it sells, including the faucet, drain connection and any fridge line, and the quote should show that labor.
Is a booster pump always needed? No. Only when pressure at your home is too low for the membrane to work efficiently.
